Metalloids that can conduct electricity at high temperatures are
called
Metalloids that can conduct electricity at high temperatures are called semiconductors.
Semiconductors are a group of elements that have properties intermediate between those of metals and nonmetals. They have some characteristics of metals, such as being able to conduct electricity, but also some characteristics of nonmetals, such as having lower conductivity than metals.
At low temperatures, semiconductors have very low conductivity. However, at high temperatures, they can conduct electricity more effectively. This is because at higher temperatures, the thermal energy causes more electrons to break free from their atoms and become available for conduction.
One example of a semiconductor that can conduct electricity at high temperatures is silicon. Silicon is widely used in electronic devices, such as computer chips and solar cells, due to its ability to control and amplify electrical signals.
In summary, metalloids that can conduct electricity at high temperatures are known as semiconductors. They have properties intermediate between metals and nonmetals and can conduct electricity more effectively at high temperatures. Silicon is an example of a semiconductor commonly used in electronic devices.

Carbohydrates contain carbon, hydrogen, and oxygen. When you eat foods that contain carbohydrates, your body uses a complex process, cellular respiration, to turn the carbohydrates into useful energy. Which carbohydrate is converted into ATP to provide energy for the cell in humans?
Answer:
Answer is Glucose because First of all lipids and lipase are not carbohydrates so they cant be the answer and the cellulose is very complex carbohydrate so it is first broken down into monosaccharides then we could use it to make ATP. Whereas, Glucose is a monosaccharide which is the simplest form of carbohydrate so it is converted into ATP to provide energy

If convection cells in the asthenosphere are the mechanism behind plate tectonic movement, what powers the convection cells?
a) energy from the sun
b) energy from the earth's core
c) air pressure changes
d) energy from magma
The energy that powers the convection cells is ENERGY from the earth's core (Option B).
Convection currents, also known as convection cells, are caused by density differences within a body of liquid or gas. Convection cells inside of the Earth form as material near the Earth's core heats up.The asthenosphere refers to the upper mantle layer beneath the lithospheric mantle which is involved in plate tectonic movement.The heat inside the Earth's core heats the asthenosphere, which is associated with the movement or 'motion' of convection cells.In conclusion, the energy that powers the convection cells is ENERGY from the earth's core (Option B is correct).

Why did life first occur in the oceans and not on Earth’s surface?
Answer:
I think because many more bacteria and cells and etc were first like created in the water, they they developed and made bigger and bigger living organisms
Answer:
Because God decided that he was gonna make animals first and he started with the ocean and then land and sky. He then made Adam to take care of all of the animals. But saw that he was lonely and made Eve with one of his ribs. He then put them in the garden of Eden with a tree that was forbidden to eat from. The tree of knowledge of the good and evil. One day eve was walking by the tree when a serpant asked her why they didn't eat from it. She replied by saying that God asked them to not eat from that tree. The serpant told Eve that God just doesn't want them to be knowledgeable like him. She took a bite of the apple and then gave some to Adam. They then realized that they were naked and made clothing from animal skin. This was what created sin. They tried to hide from God but he already knew and he banished them from the garden with angels and a fire sword at the enterance. He went to the serpant and cursed him for telling Eve to eat from the tree. Adam and Eve went on their way and had 2 boys. Cane and Abel.

Explain the process of DNA isolation.
Answer:
Lysis, precipitation and purification
Explanation:
DNA isolation is a molecular biology technique based on the extraction of DNA and subsequent purification to remove inhibitors that may hamper the process of amplification. DNA isolation consists of three steps:
1- Lysis: it consists of the mechanical disruption of the cell, where the nucleus is broken to release DNA. During this process, it is required to use enzymes and detergents such as Proteinase K
2- Precipitation: during this process, the DNA is precipitated by using alcohol and salt.
3- Purification: this process removes the impurities from DNA. Extraction is carried out by washing DNA with ethanol and water.

Imagine a glucose molecule entering the cell membrane. Would that
molecule be able to reach the mitochondria faster if the cell had a smaller
volume or a larger volume? Explain.
Answer: THE TRANSPORT OF A MOLECULE FROM THE CELL MEMBRANE TO THE MITOCHONDRIA WOULD BE FASTER IN A CELL WITH A SMALLER VOLUME BECAUSE THERE WOULD BE LESS DISTANCE TO TRAVEL
Explanation:
I hope this helped
Glucose is a simple sugar that constitutes of carbon, hydrogen and oxygen atoms. It is the most abounding monosaccharide out of all the carbohydrates.
The glucose molecule will move actively to the mitochondria from the cell membrane if the membrane has a smaller volume.
The reason for the answer is:
Smaller the cell size less will be the covering space, hence the molecule will move less distance to reach its target.Mitochondria uses glucose molecules and generates carbon dioxide as the waste material.It is not always beneficial for the cell to be larger sometimes smaller cells can be more dynamic.Therefore, the glucose molecule will travel faster when the cell membrane has a small volume.

PLEASE HELP ME Are humans predators in their ecosystem? Explain in at least 5 sentences.
Their new study shows that humans are strange predators. Unlike other animals, we target adult prey in large numbers. That is a practice that can push populations of those prey into decline, the researchers warn. People mainly target — at least among wild mammals and fishes — prey that are old enough to reproduce.
Humans are considered to be apex predators in their ecosystems due to their ability to manipulate and dominate other species through hunting, agriculture and urbanization.
Why are human predators?Humans are considered to be apex predators in their ecosystem due to their ability to manipulate and change their environment to suit their needs. Humans have the ability to hunt and consume a wide variety of other organisms, including other predators. Humans also have a significant impact on the environment through activities such as deforestation, pollution, and hunting.
However, humans are also capable of acting as stewards of the environment and preserving biodiversity through conservation efforts. The relationship between humans and their ecosystem is complex and multifaceted.

SodiumRubidiumCesium LithiumOf the elements listed, only two are found within the options for this question, which means that we can discard option C and D.
We can then proceed to analyze the atomic mass of each element in an attempt to choose the option with a lower atomic mass than Potassium. Option A, Rubidium, has an atomic mass that is much higher than the 39 of potassium, which means we can discard option A. The correct choice is option B, Sodium , since it shares similar properties and has an atomic mass of 22.

Which of the following terms are used to indicate that cell membranes will allow only certain molecules to pass through without assistance?
A. Selective Permeability
B. Open Bilayer
C. Homeostatic Membrane
D. Temporary Permeability
The plasma membrane separates the cell from the outer environment. It only allows the movement of certain molecules through selective permeability. Thus, option A is correct.
What is selective permeability?Selective permeability is the property that allows the movement and transportation of the molecules inside the cell through active or passive transportation.
It is seen in the plasma or the cell membrane of the cell as it allows only certain specific molecules to enter or leave the cell. It is important for the protection of the cell.
This allows the exchange of the nutrients and waste produced in and out of the cell. The selective permeability is the semi-permeability that is due to the lipid bilayer of the membrane.
